Explanation of some professional terms:
Spreading water, flashing water, expansion joints, settlement joints, earthquake-proof joints, construction joints, foot restraints, skirting lines,
Parapet wall
Water dispersion:
Refers to protecting the wall base around the house and dispersing rainwater away from the wall base. The protective layer generally has a width of about
800mm
. There are several types such as brick paved concrete, cast-in-situ fine stone concrete and concrete concrete. This will easily make the foundation settle more easily. Simply put, if water is not dispersed, the walls of the house will be more likely to have cracks in the future.
There is generally half a meter of cement floor from the root of the wall.
Around the house or around any building, there is about one meter from the root of the wall. It's not a concrete floor. That is water dispersion. Many buildings
have them

Flooding is a waterproofing process in buildings. In layman's terms, it is carried out at the intersection of walls and roofs, that is, at the intersection of all flat surfaces that require waterproofing
The waterproofing treatment, to put it bluntly, is to wrap the corners with waterproof materials.
Different from Sanshui
The key points of its structure and methods are:
(
1
) The membrane used to lower the roof continues to be laid on the vertical wall to form a waterproof membrane with a flashing height of not less than
250mm
(
2
) At the joint between the roof and the vertical parapet, the mortar leveling layer should be plastered into an arc shape or a 45-degree slope
, apply membrane adhesive
adhesive to make the membrane glue densely to prevent the membrane from being lifted or broken, and add a layer of membrane.
(
3
) Fix the roll end of the flashing outlet to prevent the roll from sliding down on the vertical wall. The general method is: cut a long groove in the vertical wall, press the rolled material into the groove, press it with waterproof battens, and then fill it with sealing material to seal it tightly. Protect with cement mortar.
The wall above the groove should also be waterproofed.
Popular explanation: Flooding refers to the waterproofing method of roof parapets, overhangs or high and low roof walls. Its main function is to ensure the waterproofing of parapets, overhangs and high and low roof walls.
It is not washed away by rainwater, and the waterproof layer protects the rest of the roof (from water intrusion).
Flooding is usually done on the roof

Plastering
The thickened part of the wall where the exterior wall of a building comes into contact with the outdoor ground or scattered water
The function of the foot brace is to prevent the erosion of ground water and rainwater dripping from the eaves, thereby protecting the wall, ensuring indoor dryness, and improving the durability of the building
The height of the foot brace is generally the height difference between the indoor floor and the outdoor floor.

Skicking line
Special words used in decoration
In bedroom design, the inner corner line and waist line , baseboards play a visual balancing role. Using their linear feel, materials, colors, etc. to echo each other indoors can achieve a better beautification and decoration effect.
Another function of skirting is its protective function.
The baseboard, as the name suggests, is the area that can be kicked by the foot, so it is more susceptible to impact. Making skirting can better make the connection between the wall and the ground solid, reduce the deformation of the wall, and avoid damage caused by external collision. In addition, the baseboards are also easier to scrub. If the mopping floor is splashed with dirty water, scrubbing is very convenient.
The baseboards are made of porcelain, wood, or marble.
Height of baseboards
In previous renovations, the height of baseboards was generally

About centimeters. In recent years, the height of the skirting has been gradually reduced. Most families choose

Parapet
The parapet is a form of building wall , was originally called Nüqiang, also known as Nuyuan. Its actual name is eaves-pressing wall, and it is also called battlements among the people.
It is a kind of low wall that is higher than the roof and city wall.
In terms of architectural form, the parapet is a way to connect the shape of the roof and the exterior wall. It later gradually developed into a specialized protective wall.
The origin of the parapet wall is very interesting. According to folklore, in ancient times, due to the constraints of feudal ethics, wealthy families built specially built parapets on their roofs and walls in order to prevent their daughters from going out casually. There is a wall, but girls can't help but the excitement and temptation of the outside world without leaving home, so they quietly climb up to the roof or high wall, separated by that A short protective wall looked out. Over time, it became known as the parapet. There are various architectural forms of parapets, generally including solid walls and those with lookout holes.
The origin of the name of the parapet
An ancient bricklayer was busy at work and had to take his young daughter with him. While the roof was being laid, the little girl accidentally fell into the roof and died. The craftsman was heartbroken and built a low wall on the roof in order to prevent the tragedy from happening again. Later, people named it "
Parapet Wall
"
The above is a joke.
The real origin:
Song Dynasty's "Building Methods"--
"
It is said that she is humble, compared to a woman in the city. Yu Husband
”
It is the upper part of the city wall that rises.
Parapet is an architectural term, which refers to the low wall where the outer wall of a house is higher than the roof. We can often see it in the architecture of the Ming and Qing Dynasties.
This is one of the organized roof drainage solutions.
When overhanging eaves are not desired due to the architectural shape, the exterior wall is usually raised to seal the roof. The part of the exterior wall higher than the roof is called the parapet
.
To put it simply, it means to wrap up the rainwater on the roof and collect it in one place before draining it outside the house.
If there is no parapet and no gutters or gutters, rainwater will flow down the wall in all directions, and the feet of the exterior walls are often eroded by splashing rainwater
and reduce the quality of the building. the strength and durability of the facade; rainwater dripping from the cornice may affect the sidewalk, etc. These shortcomings become more prominent when the buildings are taller and the rainfall is heavier.
As for the National Center for the Performing Arts, the Louvre Pyramid, etc., their drainage systems are very organized, and their functions are not much the same as those of parapets
It’s just a different approach.
